Specification of Letters Patent.

Patented June 29, 11915.

Application filed. December 30, 1914. Serial No. 879,652.

To aZZ whom it may concern Be it known that I, HENRY STAFFORD GOLLAND, a subject of the King of Great Britain and Ireland, residingat Dunstan, Eccles, Manchester, in the county of Lancaster, England, merchant, have invented new and useful Improvements in Means for Cross Winding Yarn in Spinning- Mules, of which the following is a specification.

The invention relates to means for crosswinding yarn in spinning mules, and is an improvement upon inventions for which I have obtained United States Patents Nos. 750,026 and 878,422. In these prior patents I described the use of an auxiliary yarn guide wire disposed between the spindle and the winding faller wire and under the yarn, which guide wire was vibrated and during the run in of the mule carriage acted upon the yarn to direct it in widely pitched spirals upon the cop nose to produce what is known as a cross-wound cop.

The object of my present invention is to simplify the means used to vibrate this auxiliary guide wire, the mechanism being also reduced very greatly in weight and bulk to that shown in my latter patent referred to, No. 873,422.

The gist and essential novelty of my invention is to vibrate the auxiliary guide wire by mechanism actuated through the winding faller shaft, which shaft I have caused to oscillate or rock upon its center during the winding operation by providing the copping rail with a wavy or undulating surface so that the windingfaller wire is raised and lowered to a slight degree several times during the run in of the mule carriage. Instead of using a wavy copping rail other means may be adopted to rock the winding faller shaft, such for instance as applying an eccentric bowl to the boot leg slide such bowl running on the copping rail.

Although I will now describe means suitcarrying my invention into effect I wish it to be understood that I do not confine myself to such means as they may be varied in point of mechanical detail. r

In the accompanying drawings which clearly illustrate the invention, Figure 1 shows a side elevation of my improved mechanism. Fig. 2 is a view at right angles thereto. Figs. 3 to 6 are detail parts. Fig. isa side view of the copping rail with in clines applied thereto, and Fig. 8 is a view -of the back copping plate and which is made to the same height and angle as the front plate such front and back copping plates being used to effect the horizontal lowerlng of the copping rail to gradually raise the position of the winding faller wire during the building of the cops.

The auxiliary guide wire referred to is marked a and is carried by fingers 6 one at each end of the winding faller shaft 0 at each side of the headstock and loosely mounted on such shaft. In addition any suitable number of sickles cl are used at intervals to carry the auxiliary guide wire a, and these sickles (Z are also mounted loosely upon the winding faller shaft.

he auxiliary guide wire a is disposed, as in my former invention, between the winding faller wire 6 and the spindles f and beneath the yarn, the winding faller wire 6 being carried by sickles g secured to the winding faller shaft 0 in the usual manner.

The mechanism illustrated in the drawings for vibrating the auxiliary guide Wire a is mounted on the winding faller shaft 0 at each side of the headstock. The drawings show the mechanism at one end of the winding faller shaft 0 only, the shaft 0 carrying duplicate mechanism for each finger b and sickle 03 along the entire length of the mule carriage. The fingers b are each provided with a stud, bowl or the like 9* resting upon a cam g, and a similar stud g" is also carried by each sickle (Z secured to a tail cl.

The ordinary movements of the winding faller shaft 0 are imparted thereto by mech anism at present in use for that purpose.

To obtain the additional oscillating movement of the winding faller shaft 0, which under my invention it is necessary it should have, as well as its usual movements, the copping rail is provided with a number of double inclines k as shown in Fig. 7 so that when the bowl it of the usual rail lever or boot slide runs up and down these inclines, the winding faller shaft 0 will be rocked or oscillated on its center. The mechanism actuated from the oscillating or rocking motion of the winding faller shaft 0 is adapted, during the winding operation, to vibrate the cam g to move the fingers I; up and down, and at the same time to rockthe cam to some extent upon, and rotate it around, a center. The extent of vibration of the cam is constant, but the vibration of the fingers b, and with them the auxiliary yarn guide a is gradually increased from a minimum to a maximum. The minimum vibration of the fingers b and the sickles d is effected at the commencement of the formation of the cop bottom when the guide wire a is to raise and lower the yarn to a minimum degree, and as the cop bottom is being formed the vibration of the guide wire a is gradually increased by rotating the cam to bring an increasing diameter of the surface of the cam into action to give a gradually increased lift to the sickles until the cop bottom is formed and the full length of chase of the cop nose is obtained. This maximum lift of the guide wire a is then maintained throughout the building of the cops. This building of the cops is effected by the action of the usual copping motion upon the winding fa-ller shaft, which, besides being rocked, is slowly rotated to very gradually lift the winding faller wire as is well understood. Nhen spinning is taking place and the winding faller wire is lifted as usual above the tips of thespindles, I

arrange also that the auxiliary guide wire a shall be similarly lifted but to a point below the tops of the spindles, so asnot to come into contact with the threads during the spinning operation.

The vibrating of the cam 9 about the center of the winding faller shaft 0 and the rocking and rotating movement of the same are effected as follows. The cam g is shown separately in face it is loose on a stud which stud is carried loosely in a bracket or part i which is also mounted loosely on c and on the same stud g is secured a spur wheel meshing with the teeth of a quadrant 9 formed on a bracket 9 mounted loosely on the winding faller shaft 0 and clamped or held to a part 9 of the fixed frame or otherwise secured to prevent it oscillating with the shaft 0. A toothed quadrant j fast on the winding faller shaft 0 and oscillating therewith gears with a toothed quadrant j loosely mounted on a stud j secured to the bracket 9 and a stud or projection j on the quadrant y" carries a bowl 7'* disposed in a slot in the bracket 6 carrying the cam g. A separate view of the bracket 9 and the parts carried by the same is shown in Fig. 3. The toothed quadrant y' is also shown separately in Fig. 6.

\Vhen the winding faller shaft 0 oscillates or rocks on its center as described during the run in of the mule carriage the quadrant j thereon actuates the quadrant 1" in gear with it and by means of the bowl 9' engaging in the slot 73 inthe cam bracket 2' vibrates the cambracket about the axis of the winding faller shaft 0, the cam 9 carried on this bracket causing the finger Z) of the auxiliary view in Fig. 5 and the winding faller shaft guide wire a to be lifted and lowered by reason of such cam acting against the stud 9* fixed on the finger b, the cam being at the same time rocked'on its center. At the commencement of the winding of the cops the stud 9* rests on the smallest diameter of the cam g as shown in Fig. 1. This provides for the minimum lift of the auxiliary guide wire a at the commencement of the build of the cop bottom. The lift of the guide wire a must be gradually increased as the cop bottom is being formed until'the proper length of chase is reached when the extent of lift or" vibration of the guide wire (6 remains constant or practically so throughout the rest of the formation of the cops. This gradually increasing lift or vibration of the guide wire a is effected by a gradual rotation of the cam 9 around its axis so as to bring the increasing diameter or incline of the cam to act upon the stud 9* of the guide wire finger 5, this rotative move-' ment being effected simultaneously with the rocking of the cam upon its own center and its oscillation about the center of the winding faller shaft 0.

The rocking and rotating actions of the cam g are effected by a ratchet and pawl motion which is arranged, through the medium of the spur wheel 9 to rock or oscillate the' cam on its center and at the same time feed it around on its axis. The motion consists oftwo ratchet wheels m n secured upon the stud 9 on which the cam g is loosely mounted, the teeth of one'ratchet' wheel being arranged at an angle opposite to the teeth of the other. The cam 9 car ries two spring pawls m n the pawl m being adapted to engage with the ratchet m and the pawl a with the ratchet n.

In Fig. 1 a part of the ratchet wheel a is broken away to show the opposite angle of the teeth of the ratchet wheel m. When the cam bracket 2' is oscillated about the axis of the winding faller shaft 0 the stud g 'is rotated in its bearing in the bracket 2' by means of the spur wheel 9 which is fixed upon it and meshing with the fixed quadrant 9*." The ratchet wheels at n being secured upon the stud g oscillate with it. The spring pawl mbeing adaptedto engage with the ratchet wheel at is pulled in one direction and being fastened to one side of the cam g pulls the cam g" which is loose on the stud 9 around its center to the extent of the movement of the ratchet wheel in that direction. hen the motion of theratchet wheel is reversed the stud "n which is fixed on the ratchet wheel n pushes the cam g in the opposite direction 'to theextent of its motion in that direction. This oscillation of the ratchet wheel m takes place "during the inward run of the mule cariage andthe winding of the yarn on the spindle, and when this is finished the movementof the fallen shaft loo 0 during the delivery or upward movement of the winding faller wire 6 to its position above the spindle point, carries the bracket 2' and with it the cam g to its highest position lifting the wire a to a position below the spindle point. The degree of oscillation of the bracket i during this movement carries the ratchet wheels around in one direction to a considerable degree but means are provided to limit the rotation of the cam 9 any farther than will bring its larger diameter beneath the stud 9*. At the point when the cam has been revolved around its center so that its largest diameter is brought beneath the stud 9*, the end m of the spring pawl m comes in contact with the concentric ledge 0 and is disengaged from the ratchet wheel m and ceases to pull the cam g any farther around in that direction. When the backing 011 takes place and the winding wires are lowered to their initial points the movement of the ratchet wheel m is reversed and the stud n pushes the cam back to its initial position the pawl m again engaging with the ratchet wheel m.

As the winding proceeds the initial position of the winding wires is gradually raised by the decreasing of the extent of the movement of the winding faller shaft 0 in the reverse direction, this also decreasing the reverse movement of the bracket i and the ratchet wheel m. The stud n likewise being reduced in its reverse movement pushes back the cam g a shorter distance each time and the cam is thus gradually fed around its center and the larger diameter of the cam g comes into operation and increases the length of movement of the wire a. When the cop has been built some distance up the spindle the reverse motion for backing off has become gradually shorter until the reverse motion of the stud n is not suflicient to effect the backward oscillation of the cam g and is inoperative. By this time the end a of the pawl 12. will be drawn out of contact with the concentric ledge 0 and the pawl n will engage with the ratchet wheel n. As soon as the motion is reversed the pawl 11, being engaged with the ratchet wheel 'n, will pull the cam in that direction until the pawl at n again comes in contact with the concentric ledge 0 when the pawl 11/ will be disengaged from the ratchet wheel 12. and cease to effect the movement of the cam g in that direction. The degree of oscillation of the cam g is now controlled in each direction by the spring pawls m, n, the extent of their pull being determined by the point at which m and n meet the concentric ledges 0 0 and disengage the pawls m, n from the Copies of this patent may be obtained for five cents each, by addressing the ratchet wheels m n respectively and alternately. The slot k in the cam bracket with which the bowl j of the toothed quadrant j engages is shaped so that the bowl 7' will not affect the position of the cam bracket after the auxiliary guide wire has been raised to its maximum height below the spindle point preparatory to the spinning operation.

It will be understood that any desired number of sickles for the guide wire a and actuating mechanism for such sickles, may be used and a suitable casing for such mechanism may be provided.

I declare that what I claim is.

In a spinning mule, means to vibrate an auxiliary yarn guide wire disposed between the spindles and the winding faller Wire and beneath the yarn to cause the guide wire to act upon the yarn and direct it upon the cop nose in widely pitched spirals to produce cross wound cops, by mechanism actuated from the winding faller shaft and means to oscillate or rock the winding faller shaft on its center during the winding operation substantially as described.
